This catagory B listed structure is all that remains of the Barony Colliery, set up in 1907 by the Eglinton Iron Company to supply coal to their Lugar Ironworks. After being Nationalised, a new shaft was sunk in the 1950's, the frame was built in 1954 and is the last of its kind in the UK. It was restored to become a monument to an industry that no longer exists in Scotland. Map location.
